To (1,55 whom it may concern.-

Be it known that we, CHARLES Tnnnro, re

seille, France, citizens of the French Re uh lic, have invented certain new and usefu In provements in HeatExchanging Apparatus, of which the following is a specification.

This invention relates to regeneretors or heat-exchanging apparatus, and hes for its object a new construction of such sp arntns which is a veryeconomiccl one and o a comperatively small bulk, While being very efficient inits action, and is adivision of our joint application, Serial No. 92,736, filed February 5, 1902.

The main feature of the present invention is that the device only consists of list arellel plates, which are superposed on held apart by means of strips arranged along the outer is es of said letes, these strips having diagonal y-op ose apertures or interruptions which 'orm large passages connected with collectors for the entrance and the exhaust of the fluids circulating between the plates.

In the accompanying drawings, Figure 1 is a planview of one of the plates, showing the arrangement of the strips and passages in the same. Fig. 2 is a similar view of the plate just above or below that of Fig. 1. Fig. 3 is a vertical section of the whole a aratus, on an enlarged scale, through lme F of Fig. 2. Fig. 4 is a vertical section, on an enlarged scale, through line G H of Fig. 2.

The rcgenerator or heat-exchanger accord ing to this invention consists of a series of thin fiat sheet-iron plates 6, which are are ranged arellel to each other and held apart at a suitable distance by means of metallic strips 0, placed along their edges. These strips form tight joints, thus converting the spaces between the plates into compartments which are entirely closed, except at two diagonally opposite edges, where the strips are interrupted, so as to form large passages, being diagonally opposed for the purpose of causing the fluid to traverse the Whole length of the compartment.

On Figs. 3 and 4 the compartments are numbered 0, 1, 2, 3, etc, so as to permit to explain that in all the divisions or compartments of even set the passages are arranged at the extremities of the same diagonal of the plates, Fig. 1, and that in all the compartments of uneven set the passages are arran ed atthe ends of the other diagonal, Fig. 2. be

cold iluid passes, say, in the uneven compartments, entering through the passages g and esca ing through the passages h. The hot fiui passes into all the compartments of the e en set, entering by the passage '5 and escaping' by the passage m.

The up aratus is inclosed into a casing c, and in or or to insure tightness at the spots where the passages g h i m traverse the casing suitable packings t, of hemp, fiber, and so on, may be arranged along the joints.

All the elements of the apparatus are ti 'htened together by means of bolts or tie-rods d.

The apparatus presents the following edvantages over the heat-exchangers as hitherto constructed: The whole surface of the plates operates in the transmission of the mat, which result is not obtained by the common construction of hestexchangers having two concentric tubes, as only the surface of the interior tube acts in this case for the exchange of heat, and the surface of the exterior tube, although greater than that of the interior one, becomes not only inactive, hut forms, on the contrary, a serious source of loss by radiation by reason of its great surface. Moreover, in such an apparatus with concentric tubes the contact of the fluids on the metallic Walls is by no means as perfect as in the present recuperetor, Where the fluids are divided into very thin layers.

The metallic separating-stri s may be replaced by stri s of hemp, pac or indierulabcr when tile temperature of t e hot fluid is moderate. The bolts and tie-rods may also be replaced by any suitable device.

Having now particularly described and as certained the nature of the present invention and in what manner it me be carried into practice, we declare that w at we claim is- A regeneretor or heat-exchanging apparatus, comprising a plurality of super ose parallel fist lstes, a pair of L-sha er strips interposed between each pair of p ates, thereby forming a plurality of so erposed compartments and constituting side and end walls for said com artments, the elon ated member of each olsaid strips arrange at the side margins of a pair of the plates and the shorter member of each of said strips arranged at the end margins of a pair of the plates, said el0ngated members of said strips of less length than -'the ien th of 'the plates, thereby form ing each of t e compartments with a pair of passages constituting an inlet and an outlet, the pair of strips in every alternate compartment alternately arranged with respect to communicating with the inlets of the other set of compartments, an outlet-pipe communicating with the outlets of one set of com partments, an outlet-pi e communicating with the outlets of the other set of compartments, means for securin the plates together, and an inclosing easing or the said )lates.

In testimony whereof we have hereunto the {pair of strips in the other compartments, set our hands in presence of two subscribing thereby alternately ositioning the inlets and outlets of one set oi compartments with rezpect to the position of the inlets and outlets the other set of compartments, an inletlpipe communicating with the inlets of one set of compartments, a separate in1et-pipe l l l l l l wltnesses.
